T0 aZZ whmn it may concern.-

Be it known that I, FREDERICK WEAVER OLIVER, a subject of the Queen of Great Brit ain, residing at 40 King Street, Oheapside, in the city of London, England, have invented certain new and useful Improvements in Apparatus for Making Paper or other Tubes, of which the following is a specification.

The object of this invention is to provide a machine by which tubes may be formed by winding pieces of paper or similar material coated with a cementing material onto a series of mandrels, one after another, and by drying or partially drying the tubes as they are formed and then automatically deliverin g the completed tubes in regular succession.

Figure l is a plan, and Fig. 2 a side elevation, of the machine. Fig. 3 is avertical section, and Fig. 4 a side elevation, partly in section, of the frames and drum. Fig. 5 is a part side elevation, partly in section; and Fig. 6, a part vertical section showing details to a larger scale.

a. is a stationary hollow drum keyed to afixed steam-pipe b, by which it is supplied with steam and so kept heated.

c is a sleeve free to revolve on the pipe I) and having fixed to it a toothed wheel 0, Fig. 1, gearing with a pinion on a shaft 0 driven by the belt-pulley c cl is an open-work frame surrounding the drum a. The hub d, Fig. 3,, of one side is in one piece with the sleeve 0, while the hub 01 of the other side runs loose on the steam-pipe b, the two sides of the frame being connected at the circumference by bolts d passing through distance-pieces (1 Figs. 2 and 4..

e e are two stationary toothed wheels, one keyed to the steam-pipe b and the other carried by a bracket 6', Fig. 1, bolted to the base of the machine.

fare arms carrying brackets f and free to move radially in guides in the frame 01, being pulled inward by springs f Figs. 3 and 6,

and being pressed outward periodically by stationary cams g, keyed to the steam-pipe b.

h are the mandrels, free to rotate axially in bearings f at the ends of the radial arms f,

r and square prolongations h, Fig. 6, of them pass through corresponding holes in toothed pinionsj, working in bearings f at the ends Serial No. 599,710. (No model.)

tionary rings of teeth 6.

k are pressing-rolls working in bearings in links is, Fig. 5, which are pivoted at to the frame (1 and at k to the radial arms f. The axes 10 Fig. 6, of the rolls 70 have fixed to them pinions k gearing with the stationary rings of teeth (2. The rolls in are normally kept pressed against the mandrels h by rods 70, Fig. 5, actuated by springs 10"".

Z are levers pivoted at Z to lugs on the hubs d d of the frame d and having holes or eyes near their ends through which the mandrels h and rolls in or their spindles 10 pass.

Z Fig. 6, are pieces engaging with grooves in the mandrels h and carrying pins Z working in longitudinal slots in the lovers Z.

l are rollers at the ends of the levers l, which come periodically against stationary cams m, Figs. 1 and 2, fixed on the bed of the machine, the levers Z otherwise keeping the mandrel closed by the action of the springs Z 12 is a table, along which sheets of paper or other material are fed by hand or otherwise between the roller 0 and feedsegment o, the

' feed-rolls p p, and pasting-rolls q g, from whence they are delivered on the platform 1, Fig. 5, pivoted at r and resting on the roller or pin 3, carried by the lever s, which is pivoted at The action of the apparatus is as follows: The frame (1, revolving continuously, carries with it the mandrels h and pressing-rolls is, which also revolve about their own axes by reason of the pinions j and 70 on them gearing with the stationary rings of teeth 6. At the lower part of their course the mandrels 71.

rolls k are not in contact with the mandrels h for the stationary cams 9 have pressed the arms f radially outward, as shown in Fig. 5. When a mandrel h comes opposite the feed, a sheet of paper, coated on one or both sides with cementing material, is thrust between it coming to the end of the rise of the cam g, is brought back by the springs f and the leading edge of the paper is nipped between the roll and the mandrel and the drum and the mandrel and is wound upon the latter. T0

of the bracket f and gearing with the sta and one of the rolls k, and then the arm f, I

are not in contact with the drum 0. -and the still further insure that the leading edge of the paper shall be wound properly around the mandrel, curved guide-segments k may be fixed on the links which when they come together form an almost continuous semicircular guide around the mandrel, leaving a space, however, between it and the mandrel, which is filled up by the paper or other material, while on the opposite side is a guide 25, pivoted at t to the frame d, which is slotted to receive pins t fixed to the spring-rods 70, so that immediately the rolls 70 move toward the mandrel h the nose of the guide comes close down onto the latter between the two rolls 76. The guide 25 carries on its back a roller i to assist in the passage of the paper. As the frame d continues to revolve, a projection d on it comes against the nose of the lever s, so raising the platform 7', as shown in dotted lines in Fig. 5, its mouth moving approximately with the mandrel.

u is a roller (in the form of a number of narrow disks separated by distance-pieces) pivoted to arms a. This rests on the paper and by its weight maintains a suitable tension.

As the mandrel revolves all the paper is Wound up onto it, and the paste dried or partially dried by the tube being kept constantly bearing against the heated drum. hen the winding is complete and the paste set, the mandrel is moved a short distance outward away from the heated drum, and the rollers and guides away from the mandrel, as above described. By means of a rise in the cams g the mandrel is then withdrawn and the tube ejected. by any suitable ejector or allowed to drop away. To enable the mandrel to be withdrawn, it is divided transversely into two halves, as is clearly shown in Fig. 6, and one half is withdrawn from one end, the other from the other. The sliding endwise of the two parts of the mandrel is effected by means of the fixed cams m, which operate the levers Z.

'What I claim is 1. The combination of a drum, a mandrel parallel to the axis of the drum and adjacent to its periphery and means for causing the mandrel to roll upon the curved surface of the drum.
